Firefighters bulldozed a fire line to prevent the spreading of a blaze that burned three to four acres of woods yesterday on Traceys Mill Road near the Linesboro Road intersection, said Chief John Krebs of the Lineboro fire company.

About 30 firefighters from Lineboro, Manchester, Hampstead, Parkville and Pleasant Hill, and a company from Glen Rock, Pa., battled the flames from about 9 a.m. until about noon.

There were no injuries, Chief Krebs said.

Steep terrain and a shortage of people hampered the firefighters.

Firefighters on 10 vehicles, including six small brush trucks and a bulldozer-plow from the state's forestry division, fought the fire, the chief said.

The Glen Rock fire crew is part of a fire company in southern York County, Pa., that specializes in forest fires.

The crew brought expertise in building fire lines, Chief Krebs said.

He said a steep hill prevented larger fire engines from reaching the blaze, so the brush trucks shuttled water to it.

At first, Chief Krebs said, only three volunteers responded to the alarm, which isn't unusual on a daytime fire.

The fire was in a logged-over woods with thick undergrowth. With that type of fire and only three volunteers to fight it, he said, "You're kind of overwhelmed.

"It was a lot of hand work because of the terrain. It was a lot of sticker bushes.

"It was just one of those days."

Chief Krebs said the cause of the fire was not immediately determined.

The Lineboro company has fought several bush fires this week. Chief Krebs said the early spell of warm, dry weather contributed to the problem.

Other woods and brush fires were reported yesterday afternoon in Reese, Silver Run and Marston. There have been more than 20 in Carroll County since last Friday.
